Divine Mercy Sunday, the new supplemental designation of the Second Sunday of Easter, was one that Pope John Paul II decreed in 2000, was a celebration close to his heart. A revelation of Divine Mercy, along with various prayers and an image, was revealed to Sr. Faustina, a Polish nun, in the 1930s. Prior to his election as Pope, Cardinal-Archbishop Karol Wojtyla started the process of her canonization and then he completed it as Pope in 2000.
Before he died, Pope John Paul II prayed with the Mass of Divine Mercy Sunday. At the Mass, celebrated by the Pope’s close friend, Archbishop Stanislaw Dziwisz, he was given the Anointing of the Sick and Viaticum. Shortly after the conclusion of Mass, he was recalled to his creator. Personally, I think it is by no means a coincidence that he died shortly after that particular Mass.
